1.前言成材率是反映钢铁工业生产经营好坏的一项重要的综合性指标。目前各个钢丝绳厂家计算成材率的方法各有不同。为了使成材率指标有可比性,我们认为应该有一套比较科学的、实用的、有可比性的计算方法。下面将我们运用的两种计算成材率的方法提出来,同广大金属制品工作者进行研究探讨。 1. Introduction Proportion of finished products is an important and comprehensive index that reflects the quality of the steel industry’s production and operation. At present, various methods for calculating the yield of various wire rope manufacturers vary. In order to make the yield rate index comparable, we think there should be a more scientific, practical, comparable calculation method. The following two methods we use to calculate the yield rate of the proposed metal products with the majority of workers to study.
